Introduction:

Bravais demonstrated mathematically that in 3-dimensions, there are only 14 different types of arrangements possible. These 14 Bravais lattices are classified into the seven crystal systems on the basis of relative lengths of basis vectors and interfacial angles.

 

Seven crystal systems are:

 

1.      Cubic

 

2.      Tetragonal

 

3.      Orthorhombic

 

4.      Monoclinic

 

5.      Triclinic

 

6.      Trigonal (Rhombohedral)

 

7.      Hexagonal
